In most previous work, performance analyses for diversity systems assumes independent fading channels, and the performance is evaluated for nonstationary fading channels with perfect interleaving, and characterized in terms of long-term parameters such as the average bit-error rate. Performance of systems utilizing an ARQ scheme depends on the dynamics of fading channels, which is not captured in long-term averaging. In this paper, based on the level-crossing rate of the received SNR, we design and build ¯nite-state Markov models representing the total power of two correlated Rayleigh fading channels. These models can provide both static and dynamic properties of correlated fading channels, and are very useful for the performance evaluation of diversity systems.
